CAN OPENER.

Application filed November 25, 1927. Serial No. 285,810.

This invention relates to can openers. Its

. an abutment for the punch itself, this latter being produced by adownwardly turned angular incision inthe resilient portlon of 1B thefolded over portion so positioned that a smart blow upon it depressesthe. member and the sharp pointed angular projection thus piercing thecontainer. v v The drawings herewith forming a part of the applicationshow the details of the device 'more exactly. In these Fig. 1 is a Viewof the flat metal stamping. Fig. 2 is a side View of the deviceascompleted and in the operativeposition on the-top of a can orcontainer. Fig. 3 is a plan view from above, and Fig. 4 is a similarView from below.

In these drawings the numeral 5 indicates a can or container forcondensed milk or the like, 6 a fiat metal stamping formed with the twoprojections 7 which when turned right-angularly to the surface of thestamping 6 form with the'edge of the can a gauge or abutment at 8. Thestamping is further incised at 9 and 10. The latter when also desire tobe turned right-angularly provides the spike 11 3 for piercing the coveror end of the can.

The extremity 12 of the stamping is folded over so that the spike 11 ispositioned between the projecting tangs 7 as shown in Fig. 2. and thelongitudinally central in- -cision 9 is bent angularly to form thehandle 13.

The operation of the device is obvious from the drawings. The tangs 7are clipped over the edge of the can in the position in-, 4 dicated at 8and held there by the handle 13,

a smart blow is then given u on the folded member 12 by any handy harobject causing the spike to perforate the top of the can and the processrepeated on the opposite edge to form an air inlet. Having nowparticularly described my invention, I declare that what I claim andprotected in by Letters Patent, 65 1s: K

A device for a can perforating tool comprising, a flat stamping ofsubstantially rectangular elongated form and having one of its endbifurcated by the removal of a central U-shaped portion, an elongated U-I shaped incision in the body of said flat stamping, the open end of thelast said U- shape being ad acent the said bifurcation, and a secondincision of substantially V- shaped form adjacent the end of the saidstamping opposite the bifurcation.

In testimony whereof I aflix my signature.
